RAYMOND SLIDER OPERATING CLOSURE Filed Aug. 25, 1951 2 Sheets-Sheet 2 Patented Jan. 31., 1933 ALBERT VICTOR RAYMOND, OF GRENOBLE, FRANCE SLIDER OPERATING CLOSURES Application led August 25, 1931, Serial No. 559,307, and in France August 28, 1930.

The present invention relates to improvements inthe type of closures consisting of two fiexible stri s-or bands (of tissue, cloth or other materia s) which are provided with rows of fastening elements adapted to be interlocked by means of a slider, this slider being able to slide freely along said fiexible strips. l

These strips or ribbons are generally connected at one of their ends by a fixed tie and it is therefore impossible to Wholly remove one of them fromthe other, when operating the slider for unlocking.

This feature is of great disadvantage for 5 many uses, when a complete separation of the strips or bands is absolutely re uired. If the separation and reconnection o the strips with their interlockin fastenin'o'elements could be easily eflecte these slider-operato ing closures would find important new applications for many goods, personal wears, etc.

One of the objects of my invention is to provide a new and improved device for closures of said type, which enables to wholly remove one of the interlocking strips from the other, each of these separated strips alwa s keeging its row of fastening elements.

furt er ob'ect is to provide a new device which ena les to easily reconnect the two separated strips with their interlocking elements by joining their edges at their extremity. Y

According ,to my invention, the said device consists essentially in a guide member,

for instance a metallic one, to be fixed on one of the strips,said member enclosing and retaining, when both strips are connected, two riular rigid members fixed to the end 0f ea l stri for the purpose of joining said 4 stri s toget er at thelr extremities.

is guide member is so devised as to a1- low the slider to penetrate thereinto, and elastic means, preferably including a sliding member and a spring, are adapted to. cooperate with said guide member in such manner as normally to prevent the slider from moving as far as the end of the two rows of interlocking fastening elements, so that said last elements remain interlocked. However said elastic means are adapted to yield to an increased effort so that the slider may move further and separate the last interlocking elements. It is then possible to remove one of the tubular rigid members from the guide member 'and thus to separate the two strips. 55

. In order that my invention may be full understood it will first be described with re erence to the accompanying drawings and afterwards more particularly pointed out in the annexed claims, my invention being not 00 particularly directed to or limited to any special type of fastening members.

In the accompanying drawings, wherein is shown a preferred embodiment of my invention:

Figs. 1 to 3 show the device according to the invention, the last fastening elements bein still interlocked.

ig. 1 is a front view of said device mounted on the end of both closing strips.

Fig. 2 is a section on the line 2-2 of Fig. 1.

ig. 3 is a section along the line 3-3 of Fig. 1.l

Fi Vand 5 show the same device after 75 the s ider has been brought at the extreme oint of its stroke, thus unlocking the last. astening elements.

"Fig, 4 is a front view.

Fig. 5 is a sectional side view on the line 80 5-5 of Fig. 4. l

Fig. 6 is a detail view showing in perspectlve one of the parts of the device according to my invention.

As shown in the drawings, two metallic tubular members c are secured, along a predetermined length to the edge of l extremity Aof each strip a and b, said s-rips carrying in a known manner the fastening elements a1, b1 which can be, separated and refastened 9 is drawn down to the'bottom of the by means of the slider j with its operating piece jl.

A guide member ,Lpreferably made up of a metal sheet, is xed at the end of one of the strips, for 'instance at the extremity of the strip b (Fig. 1). L,

Said guide member surrounds" the metallic tubular member c that corresponds to strip b and is adapted to slidably receive the metallic tubular member c of strip a, so that said members c are disposed side by side in guide member d.

A socket e can slide inside guide member d. As shown in thedetail view of Fig. 6, said socket consists of aI rismatic structure, open at the top and Yprovided with a flange 2, and the bottom of which is provided with openings for membersc. Said socket is slidably mounted in guide member d in such manner that its upward motion therein is limited by flange 2 butting against the top of said guide member.

A spiral spring f, fitted in guide member d and bearing upon the bottom of said guide member, is adapted to act upon said flange 2 so as to constantly tend to maintain socket e in its u per position inside guide member d,- by app ying said flange 2 against the under side of the to of said guide member.

To wholly isengage the strips, the successive operations wil be as follows:

The fastening elements are unlocked 'by operatin the slider j to ride until it knocks against t e edge h of the socket e (Figs. 1 and 2 then, the slider is further operated in suc manner that it draws down the socket e to the bottom of the guide member d, thus compressing the spring f and unlocking the last fastening elements g. (Figs. 4 an 5). Keeping then the slider in this position, one can easily take ofi' the flexible strip a in the direction of the arrow F for wholly removing it from the guide member d and then from the slider j.

When the reconnection of the extremities of the striis is desired, the same operations are efecte in the reversed way: the socket".1 e ui e member d by operating the slider j, and ereafter the end of the stri a is introduced into the channel of the slidr and carefully enaged to the bottom of the guide member.

y releasing then the slider, said slider is drawn u wards by the socket e under the action-o the spring f. The first fastening elem nts are thus interlocked and it only remains to draw the slider to its closing position.

What I claim is 1. In a separable fastener includin two flexible strips of flexible material eac carrying a row of fastening elements adapted to be interlocked and unlocked by means of a slider, an end closure comprising in combination, a guide member secured to the end off Aremain interlocked said s rin e5 .at

one of said strips and adapted to slidably receive the end of the edge of the other strip, and elastic stop ing means. adapted to cooperate with said guide member for normally preventing the slider from moving as far as the end of the two rows of fastening elements, so that the last elements of said rows normally remain interlocked, said elastic stopping .means being adapted to yield to an increased effort exerted on the slider, so that said last elements of the two rows may then be disengaged from each other, and the strips fully separated.

2. In a separable fastener including two iiexiblestrips of flexible material each carrying a row of fastening elements adapted to be interlocked and unlocked by means of a slider, an end closure comprising in combination, a tubular metallic member fixed to the end of the edge of each of said strips, a guide member secured to the end of one of said strips surrounding the tubular member fixed to said strip and adapted to slidably receive the other tubular member, so that said tubular members may be dis osed side by side in said guide member, and elastic stopping means ada ted to cooperate with said gui e member or normally preventing the slider from moving as far as the end of the two rows of fastening elements, so that the last yelements of said rows normally remain interlocked, said elastic stopping means being adapted to yield to an increased effort exerted on the slider so that said last elements of the two rows may then be disengaged from one another, and the last mentioned tubular element removed from the guide member.

3. In a separable fastener including two flexible strips of flexible material each carrying a row of fastening elements adapted to be interlocked and unlocked by means of a slider, an end closure comprising in combination, a tubular metallic member fixed to the end of the edge of each of said strips, a guide member secured to the end of one of said Y 'of said socket being adapted to engage t e corresponding edge of said slider, aspring for applying said socket against the top of said gui e member, for normally preventing ysaid slider from moving as far as the ends of the two rows of fastening elements, so that the last elements ofthe rows normally beingY adapted to yield to an incre rt exerted on the slider so that said last elementsof the two rows mag' then be disenga ed from one another an the last mentione removed from the guide member.
